Upgrading the Graphics Card in a GL12CM-DS761

Hello,

I just saw that the RTX 2060 Graphics card came out, and it looks to be a massive improvement over the GTX 1060. I was looking at upgrading to the ROG STRIX version of the RTX 2060 for the extra performance and LED. How doable is this upgrade, and what should I consider before upgrading? I also know to keep in mind that there is only a 500W power supply, and that may need to be bumped if this is done as well.
